A patent from Nintendo suggests that they're working on a magnetic joystick system, aka hall effect joysticks, which would solve stick drift.
A patent filed by Nintendo suggests that they’re working on Hall Effect style joysticks for the Switch 2 that would eliminate stick drift almost entirely.
I have had this problem like 3 times, I have sent my joycons for repair and I always get new ones. Not sure how Nintendo is making money out of this.
